History

Traditional music from the island consists of choral singing and
chanting, similar to Tahitian music.
Families often performed as choirs, competing in a hotly disputed
annual concert. They were accompanied by a trumpet made from a conch shell
and a percussivedancer jumping onto a stone which is set over a
calabashresonator. Other instruments include the kauaha, the jaw bone of a horse,
upaupa, an accordion, and stones, which are clapped together
for percussive effect.

Due to ongoing contacts with Chile and elsewhere in South America,
Latin American music has had
influences on the music of Easter Island. Tango, for example, has spawned an Easter Island
style called tango Rapanui,
characterized by a simple guitar
accompaniment instead of the frenetic bandoneon.
